The book 6

A boy read 3/8 of a book on one day and 4/5 of the remainder on another day. If there were 30 pages still unread, how many pages did the book contain?

Final Answer:

n =  240

Step-by-step explanation:

a=83=0.375 b=54 (1a)=54 (183)=21=0.5  r=a+b=83+21=83+84=83+4=87=0.875 R=1r=187=81 887=8887=887=81=0.125  R n = 30  n=30/R=30/81=30:81=30 18=130 8=1240=240
